Definitions

  • the present invention relates to a continuous strip of bags of the type used in bag dispensing machines commonly known as "shirts”, which have a wide notch between the two side handles. These bags are united at the start between them, thus forming the strip on which are practiced dotted lines placed at the upper part of the handles, which allows to separate each bag from the one that follows it. This is done by exerting an action by means of traction located in the dispensing machine, but it often happens that under the effect of this traction the bags become wrinkled and even manage to tear at the narrow points of union and weak handles.
  • this not only has been eliminated disadvantage, but also made a saving of plastic material, by obtaining a greater recoverable rest on cutting thanks to the die-stamping of the material which causes an opening which replaces the single cut of the first embodiment, which also makes it possible to obtain a aesthetic result superior to that achieved so far with the shirt type bag.
  • FIG. 1 If we first consider the embodiment shown in Figures 1,2 and 3, we can see that it consists of a conventional tubular strip, flattened and continuous (1), flexible plastic material, which has , on its longitudinal edges, folds (2) directed inwards.
  • the strip (1) comprises transverse weld lines (3) which constitute the respective bottoms of the bags, and dotted lines (4), also transverse and close to the preceding ones, which make it possible to separate each bag from the one which follows it.
  • a longitudinal oblong opening (10), parallel to the longitudinal edge of the strip (1), is formed by stamping on each line of internal fold (-2a) of each longitudinal fold; in this way, the longitudinal edges of this oblong opening (10) are arranged each on each side of the internal fold line (2a), and one of its transverse edges (11) is placed on the dotted line (4) or between the latter and the corresponding adjacent weld line (3), constituting the bottom of a bag, while the other transverse edge (12) is of substantially semi-circular shape.
  • the vending machines which supply bags from a continuous strip (1) are normally provided with a member which detects the passage of each bag to be supplied; the components of this detector member are arranged on each side of the strip (1) and carry out this detection by means of the notch presented by the bags of the shirt type.
  • the bag which is the subject of the present invention does not have this notch so as not to weaken its body and to be able to resist without wrinkling or tearing the tensile forces produced by the mechanism of the machine which separates it from the rest of the strip ( 1)
  • each side of the bag has openings or optical signals (7) of a size which allows the detector body to signal the passage of each bag.
  • each bag separates from the one which follows it when the strip (1) is torn along the dotted lines (4 ), which makes it possible to create, in each bag, from these lines and the cuts (5), two wings (8) which fall respectively on the external faces of the bag.
  • the weld lines (6) join the faces of the strip (1) with the fold (2) so as to form the handles (9), as can be seen in Figures 3 and 5.
